Abstract
The utility model discloses an anti-floating anchor rod construction protection device which comprises a first sleeve and a second sleeve, wherein the first sleeve is sleeved on an anti-floating anchor rod steel bar structure, the second sleeve is sleeved on the first sleeve, the lengths of the first sleeve and the second sleeve are not smaller than the length of an anchoring section of the anti-floating anchor rod steel bar structure, an annular gap is formed between the outer wall surface of the first sleeve and the inner wall surface of the second sleeve, and foam is filled in the annular gap. According to the utility model, the sleeve is sleeved on the steel bar structure of the anti-floating anchor rod to protect the steel bar, so that the anti-floating anchor rod forming quality caused by corrosion of the steel bar is avoided; meanwhile, the outer second sleeve is matched with the hole provided with the anti-floating anchor rod, so that mud is prevented from entering the hole, and the concrete quality of the anti-floating anchor rod is protected.
Description
Technical Field
The utility model relates to the technical field of auxiliary facilities for building construction, in particular to an anti-floating anchor rod construction protection device.
Background
At present, high-rise buildings mostly adopt a building form that a high-rise tower is provided with a basement with a large chassis, and in places with higher underground water level, pure underground chamber parts without upper high-rise structures have anti-floating problems.
However, in recent years, with the increase of anti-floating projects, cracks are generated on floors, beams or beams, plates and columns of basements due to floating of basements caused by insufficient anti-floating or insufficient anti-floating recognition, and the cracks have great influence on the whole projects. The construction quality of the anti-floating anchor rod is very important. And transfer the steel reinforcement cage after the in-process pore-forming of anti-floating anchor rod construction, the reinforcing bar often can be corroded before not slip casting, and mud also can get into in the hole to cause disconnected stake, influenced anti-floating anchor rod quality.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides the anti-floating anchor rod construction protection device to improve the quality of the anti-floating anchor rod.
In order to realize the purpose, the utility model adopts the technical scheme that: the utility model provides an anti-floating anchor rod construction protection device, is located including being used for the cover to locate first sleeve pipe on the anti-floating anchor rod steel bar structure and cover second sleeve pipe on the first sleeve pipe, first sleeve pipe with second sheathed tube length is not less than anti-floating anchor rod steel bar structure's anchor section length, first sheathed tube outer wall with annular gap has between the internal face of second sleeve pipe, the annular gap intussuseption is filled with the foam.
Optionally, the second sleeve is matched with a hole in which the anti-floating anchor is arranged.
Optionally, the first sleeve and the second sleeve are PVC pipes.
Due to the adoption of the technical scheme, the utility model has the following beneficial effects: the sleeve is sleeved on the steel bar structure of the anti-floating anchor rod to protect the steel bar, so that the anti-floating anchor rod forming quality caused by corrosion of the steel bar is avoided; meanwhile, the second sleeve on the outer layer is matched with the hole provided with the anti-floating anchor rod, so that mud is prevented from entering the hole, and the concrete quality of the anti-floating anchor rod is protected; the rigidity of the second sleeve is increased by filling foam in the gap between the two layers of sleeves, so that the second sleeve is prevented from being damaged by pressure, and the foam is light and convenient to carry; the protective device is taken out when the reinforcing steel bar is bent and anchored in the later period, so that the recycling is realized; the device has the advantages of convenient use, simple and light structure and low cost.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without creative efforts.
Fig. 1 shows an overall structural schematic diagram of the anti-floating anchor rod construction protection device.
Detailed Description
The following embodiments of the present invention are provided by way of specific examples, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The utility model is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.
The utility model is described in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1, the anti-floating anchor rod construction protection device according to the embodiment of the present invention includes a first sleeve 1 sleeved on the anti-floating anchor rod steel bar structure and a second sleeve 2 sleeved on the first sleeve 1, wherein the lengths of the first sleeve 1 and the second sleeve 2 are not less than the length of the anchoring section of the anti-floating anchor rod steel bar structure, an annular gap is formed between the outer wall surface of the first sleeve 1 and the inner wall surface of the second sleeve 2, and foam 3 is filled in the annular gap.
Wherein, first sleeve pipe 1 is prefabricated according to anti-floating anchor rod steel bar structure's size, and second sleeve pipe 2 is prefabricated according to the hole size that sets up this anti-floating anchor rod. The upper end of the steel bar structure of the anti-floating anchor rod needs to be reserved to be higher than the hole by about 1m for anchoring into the steel bar of the bottom plate after subsequent bending, and therefore prefabrication is carried out according to the length of the steel bar in the hole when the first sleeve 1 and the second sleeve 2 are prefabricated.
When using, establish on steel bar structure through 1 cover of first sleeve pipe, avoid reinforcing bar and earth muddy water contact, thereby the prevention reinforcing bar corrosion, the hole that collapses is prevented to second sleeve pipe 2 through 1 outer lane of first sleeve pipe and hole size matching simultaneously, and the clearance intussuseption between first sleeve pipe 1 and second sleeve pipe 2 is filled with foam 3, through 3 rigidity of this foam reinforcing second sleeve pipe 2, avoid second sleeve pipe 2 to cause the damage under the pressure of earth, foam 3 also has the effect of isolated earth simultaneously, dual guarantee, and foam 3 is light, convenient transport.
In this embodiment, first sleeve 1 and second sleeve 2 are the PVC pipe, comparatively lightly facilitate the use, and the cost is lower simultaneously.
It should be noted that the structures, ratios, sizes, and the like shown in the drawings attached to the present specification are only used for matching the disclosure of the present specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions of the present invention, so that the present invention has no technical essence, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.
